Abstract

Since this laminated body having a silicone rubber and, at least in a section of a surface thereof, a layer of a cured product of a silicone-modified-polyimide resin composition that contains, for example, components (A), (Bc), and (C) possesses elasticity and allows wiring by means of a conductive paste thereon, such a laminated body is suitable as a base material of an electronic device. The component (A) is a silicone-modified polyimide resin in formula (1)Ee-Ff-Gg  (1){where E is represented by formula (2); F is represented by formula (3); G is a bivalent group derived from a diamine; f+e+g=100 mol %; the molar ratio f/(e+g) is 0.9 to 1.1; and e is 1-90 assuming that the sum of e and g is 100 (Ris a bivalent hydrocarbon group, Rand Rare alkyl groups, Rand Rare monovalent aliphatic hydrocarbon groups, Rand Rare aryl groups or the like, m is an integer of 0-20, n is an integer of 1-20, o is an integer of 0-20, and m+n+o is an integer of 1-30)-Im-X-Im-  (3)(Im is a cyclic group containing a cyclic imide structure, and X is selected from a single bond, O, and so forth)};
